There can be some interactions or potential interactions between conventional medicines and herbal treatments and food supplements that are used to treat or prevent Flu, hence the Flu-Caution section. These interactions can vary. Some drugs may increase or decrease absorption or excretion of vitamins and minerals and some supplements can affect uptake of medicines. It is important to discuss with your coordinating therapist which supplements, herbals or medications might be of benefit in your personal strategy.
There are no published studies and there is very little information available on interactions of antivirals such Tamiflu and Relenza with supplements and herbs. This does not mean that interactions do not exist so it is best to discuss treatments with a qualified professional medical herbalist.
NSAIDs (Nonsteroidal antiinflammatory drugs ) such as ibuprofen, paracetamol aspirin etc are known to be affected by a number of vitamins and herbal remedies that can increase NSAID blood thinning properties. Take care with bromelain, dong quai, feverfew, garlic, ginger, ginkgo, saw palmetto, St John's wort, white willow and vitamin E.
Decongestants such as pseudoephedrine and phenylephrine can interact with herbal preparations such as ephedra and others.
The Flu-Caution page will be updated as new information becomes available.
